Abstract

Dialkyl diselenides have been prepared from alkyl halides, sodium borohydride and elemental selenium using two different methods. One of them involves the intermediate formation of diselenide dianion equivalent (^-SeSe^-).

Key words

elemental selenium - sodium borohydride - alkylation - alkyl halides - benzyl halides - dimetal diselenide

Synthesized by protonation (formic acid, 2.5-4 equiv) of selenide dianion equivalent [from elemental selenium, NaBH₄ and EtOH (1:2:6) in DMF]. [13a]

Typically mixing elemental selenium, NaBH₄ and EtOH (1:1:3 molar equiv each) leads to the evolvement of dihydrogen (2.58 molar equiv, 86% of the expected amount), sequential addition of DMF and decyl bromide produces an additional formation of hydrogen (0.42 molar equiv, 14% of the expected amount).

<A NAME="RG02005ST-15">15</A> We have been unable to determine the structure of these species by ⁷⁷Se NMR. For a related work see: Cusik J. Dance I. Polyhedron 1991, 10: 2629

in fact, we found in a control experiment that 6 molar equiv of dihydrogen escape from the medium (experimentally 97% of this amount) on reaction of selenium, NaBH₄ and EtOH (1:2:6 mol equiv).

Another 0.81 molar equiv of dihydrogen is evolved if aq EtOH (4 molar equiv each), is added before that of the second crop of elemental selenium.
